Get images for slider from specific folder

Kirby 2 Solved ✅
1

Hey everybody,

I’m trying to make my own small portfolio with kirby. For the moment everything works really good, except one issue with my slider.

I have my slider images in a separate folder called “slider” and something with my code seems to be wrong. I only know php a little bit, so I#m not sure about what is wrong. I already tried some different variations of this snippet, with brackets and with etc. but I didn’t get it working for 2 days, so I thought I have to ask the experts.

Here is my code in the static HTML:

<div class="slider">
  <ul class="rslides" id="home-slider">
    <li><a href="#"><img src="slider/image1.jpg" alt=""></a></li>
    <li><a href="#"><img src="slider/image2.jpg" alt=""></a></li>
    <li><a href="#"><img src="slider/image3.jpg" alt=""></a></li>
  </ul>
</div>

And here is my latest try how to get it working (imageLink is a meta-information given by me…)

<div class="slider">
  <ul class="rslides" id="home-slider">
    <?php foreach(page('slider')->images() as $image): ?>
      <li><a href="<?php echo $image->imageLink(); ?>"><img src="<?php echo $image->url() ?>" alt=""></a></li>
    <?php endforeach ?>
  </ul>
</div>

Any suggestions what is wrong in my for loop?

Thank you very much :slightly_smiling:

What is the output you get? Any error messages? Where is the slider folder located?

3

Also, the method $image->imageLink() does not exist by default. Does that come from your image meta file in your case?

So it seems …

Why don´t you use $image->url().

I have made a snippet for the bootstrap carousel. Maybe it helps to take a look at this file

He does for the image source.

Sorry, i only saw the first part of that code line

But I also don’t understand, what he wants to achieve with imageLink() and why the url of the image is not enough to link to the image.

8

I guess, the image is supposed to link to something else, maybe a website project but let’s wait and see …

Yes, I want to link to a specific project, that’s why I have this extra meta information… I happened, that I couldn’t see anything from the content under the slider. The slider folder is located in the normal content folder.

But I solved this issue 2 minutes ago. I just forgot to close the img-tag in the end. The snippet works perfect now :slight_smile: But thank you anyway! When you think about it for too long you oversee the basic mistakes -.-

<div class="slider">
  <ul class="rslides" id="home-slider">
    <?php foreach(page('slider')->images() as $image): ?>
      <li><a href="<?php echo $image->imageLink(); ?>"><img src="<?php echo $image->url() ?>" alt=""/></a></li>
    <?php endforeach ?>
  </ul>
</div>

Do you use the HTML5 doctype? It shouldn’t make a difference there.

Hi.

I used the plc-carousel for my website, but it doesn’t work.
The site appeared only to the line I have used <?php snippet(‘plc-carousel’).

There is a folder “carousel” with images in my page where I want to use the slider.
And I added the constants to the config.php.

Has anybody an idea what I’m doing wrong?

Thank you so far.

Looks like you have to pass some variables to the snippet call:

snippet('plg-carousel', array(
'currentPage'=>$page,
'preNormal'=>'optional html to add before carousel',
'preAlt'=>'html if snippet is not displayed (for other styles)'
))

preNormal and preAlt seem to be optional.

Ah! Yepp. That works. Thank you for your fast reply.

I’m a beginner with php and kirby.
Could you give me a little hint what’s the difference between $currentPage and $page in this case?

Thanks
Daniel

That’s just how the snippet is built, it’s specific to that snippet, not to Kirby. :slight_smile:

My snippet must know the page it has been called from to search for the carousel folder, so you pass the $page object to the snippet.
It’s common in kirby to pass all the arguments to a snippet in an array and currentPage is only the name of the argument, so that I can access the passed information in my snippet.

PS: I think, it would be better, if you had opened a new thread, because your question was not directly associated with this thread.
Or even better: simply write me an email or open an issue on the github page of the plugin directly.

Thanks for this explanation.
